HYDRAULIC OR FIRE HOSE.

SPECIFICATION forming partof Letters Patent No. 706,466,` dated.'August` 5, 1902; l

Application nea January 2, 1902. serial No. 88,211. (No man.) A

duced in weight and made light enough to compete in this respectthat is to say, in point of lightness-with cotton hose. Tothis end' the hose which I have devised is composed of a rubber-lined seamless single-ply tubular fabric and one or'more plies of frictionedi7 or cemented and preferably biased duck applied to the exterior of the tubular single-ply seamless inner fabric, the whole being vulcanized together, with an outer covering of rubber.

I will first describe by reference to the accompanying drawings the manner inwhich my invention is orA maybe carried'into eect and will then point out in the claimsfthose features which'I believe to be new and of my own invention.

In the drawings, Figure l represents in perspective a piece of frehose embodying my improvement, the'dierent plies being broken away to expose those beneath. Fig. 2 `is`a` view of a modification. Fig. 3 is a cross-section of the hose.

A is the seamless inner woven single-'ply fabric tube. 13` is the rubber lining therefor.:`

C is thebiased duckcovering, whiehislaid4 on the inner ply in'one,'t`wc, or three or more plies, as desired, and is designed to protect the inner seamless ply against abrasion, wear," dre., and D is the outer rubber coat.

To make this hose I proceed as follows: I take a seamless fabric tube A, whichis made very light, but of a strength sufficient to endure the strain to which hose in practical firedepartment service is subject. This tube I rubber-line, as at B, and Ialsolpreferably friction its exterior-that is to'say, thinly coat its exterior surface with adhesive rubber. The inner fabric can also be a`ntiseptic-` ally treated, if desired, to prevent decay.v Within this prepared tubular inner ply I insert a steel mandrel or apply sufficient internal pressure to cause the tubular prepared fabric to be rigidlydistended and itself act as a mandrel, and rI then applyto itthe outer .wrappings of duck C and the exterior ply D of `rubber and then cure or vulcanize the hose in"`tl1e usual way.A The duck C prior to its application is frictionedethat is tolsay, is thinly covered on both faces withadhesive rubber-so that it willwhen applied adhere to the inner ply,`the outer*rubber'1ply,"and,to itself. In lieu of frictioning the duck I can `coator surface it with rubber-cement for the purpose of securing the adhesion of the plies.

The duck is preferably biased in order to make the hose more pliable and to equalize the strain. The biased effect is obtained in Fig. l by taking a duck strip having the Warps longitudinal and .winding it spirally around the inner ply. It is obtained in Fig. 2 by taking a bias-cut duck strip of the length of the mandrel (or hose section thereon) and of a Width sufficient to encircle the inner tube one,-two, three, four, or more times,4 according to the number of plies desired, and then wrapping this strip upon the `inner tube. The duck,however, may have its warp parallelwith the axis ofthe hose, if desired, or one or more of its plies may be straight and one or more may be biased. It is generally preferred, however, that the duck shall be biased. In this way I secure not only greater initial strength for the hose,but also a strength that is not liable to be impaired by the abrasion or service, as the strength is -inherent in thevseamless inner ply,`which` cannotb'ecome wornfuntilnthe inclosingplies of duck are worn away. Hose thusmade,` `while of` comparatively light weight, is of ample strengthfor flre-department service, is not liable to cony tractin length or elongate or expand excessively, and its outer surface, as above stated, may be considerably worn without vitally or materiallyreducing the strength of the hose. The rubber covering l) can be ofV any thickness desired. Indeed, it may consist of the outer friction coat upon the duck, which will serve as a light covering when vulcanized.

4In Fig. 3, which is a cross-section of the hose embodying my invention, the outer duck .wrapping C is composed ofv apiece of frictioned duck wrapped twice around the seamless inner fabric tube A, the outer frictioned coat upon the duck serving as a light rubber IOS covering D. The thickness of the frietioned coat in this figure is somewhat exaggerated in order to better illustrate the structure of the hose as a Whole.

What I claim herein as new, and desire to secure by Letters Patent, is v Hydraulic hose consisting of an inner seamless fabre rubber-lined tube, and an outer Wrapping of rubber-coated (luck upon said inner tube, the Whole vulcanized together as r set forth.

In testimony whereof I have hereunto set myhand this 16th clay of December, 1901.
